Phase II study of dedicated silicone stent placement on the carina between the bronchus to the right upper lobe and bronchus intermedius - Dedicated silicone stent placement on the right secondary carina

The study stent could be mounted successfully on the primary right carina in all 10 patients. Five patients underwent stenting using only the new stent, and the other 5 underwent stenting with it on the primary right carina and a silicone Y-stent on the main carina. The dyspnea index improved in 8 of 10 patients, including one mechanically-ventilated. Early complications developed in 3 patients (temporary pneumonia in 2 and retention of secretions in 1), and late complications occurred in 2 patients (granuloma formation in 1 and hemoptysis in 1).
